Benefits of technology

The device includes a lens that turns the laser beam into a collimated beam wherein the rays from the smaller dispersion angle provides a narrow illumination area and the rays from the larger dispersion angle provide an elongated illumination area. Optionally, the elongated illumination area is at least twice the size of the narrow illumination area. In some embodiments of the invention the illumination area forms a rectangular area. Alternatively, the illumination area is an ellipsoidal area. Optionally, the beam provides eye safety as a result of the dispersion, which provides less intensity per unit area.
In some embodiments of the invention, the mon...

Embodiment Construction

FIG. 1 is a schematic illustration of a handheld low-level laser therapy (LLLT) device 100 for performing laser therapy, according to an exemplary embodiment of the invention. In an exemplary embodiment of the invention, device 100 provides as output an elongated monochromatic coherent laser beam 170 that is collimated by a lens directly from the natural divergence of a laser diode embedded in device 100. In contrast to prior art devices, instead of focusing the laser beam from the laser diode to a single spot to have a stronger illumination on a single spot, the natural tendency of the laser diode is exploited to form an elongated beam to cover a larger area. The standard laser diode typically has a divergence of about 5-7 degrees along its width and about 30 to 40 degrees along its length. Instead of using a lens to correct the beam to a narrow beam, device 100 uses a lens to form a collimated elongated beam to cover a larger area, for example an area of 3-6 cm by 0.5 to 1 cm. In ...

Abstract

A laser therapy device, including: a laser diode that is adapted to produce a monochromatic laser beam; a lens that is adapted to receive the beam directly from the laser diode and exploit the natural divergence of the laser diode to form an essentially coherent monochromatic, collimated beam; wherein the formed beam is adapted to form on a plane perpendicular to the direction of propagation of the beam an elongated illuminated area in which the length of the illuminated area is at least twice the size of the width of the illuminated area; a controller that is adapted to control activation of the laser diode; an encasement enclosing the laser diode, the lens and the controller; wherein the encasement is adapted to be hand held by the user.

Description

FIELD OF THE INVENTIONThe present invention relates generally to a handheld low energy laser device for treating people and animals.BACKGROUND OF THE INVENTIONThe use of light for treating people and animals is well known. Since the early history of mankind people have used the light from the sun to help cure ailments. In the mid 20'Th century attempts were made to use concentrated light for treating wounded soldiers in World War II. In later years, the laser, which is based on the quantum phenomenon of stimulated emission, provided an excellent source of concentrated light for treating patients. The laser allows the use of a selected intensity of a monochromatic, and essentially coherent. This has been found to be effective in treating people for various ailments.The use of a carefully selected wavelengths coherently directed toward a person provides energy for selectively stimulating processes in living cells. This can help increase blood flow; excite cell activity and intensify i...
